| Abstract:
Purpose: To evaluate visual acuity and refractive error after deep anterior lamellar keratoplasty (DALK) using Anwar's technique in patients with post-LASIK ectasia.
Methods: Pre- and postoperative data of patients who had developed ectasia after LASIK and hence underwent DALK by Anwar's technique were compared. Main outcomes measures were uncorrected visual acuity (UCVA), best spectacle-corrected visual acuity (BSCVA), spherical equivalent refractive error, mean keratometry and keratometric stigmatism.
Results: Eleven eyes of 10 patients were included. Mean age was 31.6±7.4 years and mean follow-up period was 20.2±6.5 months. Intraoperatively, a bare Descemet's membrane was successfully achieved in all cases.
Mean UCVA and BSCVA were increased from 20/400 to 20/160 (P=0.39) and from 20/160 to 20/40 (P=0.007), respectively. Mean spherical equivalent refractive error was increased from -11.53±5.4 D to -13.47±0.5 D (P=0.34). Mean keratometry and keratometric astigmatism remained unchanged.
Conclusion: DALK using Anwar's technique is a safe and reproducible procedure for post-LASIK ectasia.
However, a high refractive error should be expected postoperatively.
